Answer:
The other endpoint is (-4, -5)
Step-by-step explanation:
We know the formula for the coordinates of the point dividing the line segment in the ratio of a : b is
x = x' +
y = y' +
Now we plug in the values of endpoints (8, -1) and (x, y) with a point (5, -2) dividing the segment in 1 : 3 ratio.
5 = 8 +
5 - 8 =
(x - 8) = -3×4 = -12
x = -12 + 8 = -4
Similarly, -2 = -1 +
-2 + 1 =
y + 1 = -1(4)
y + 1 = -4
y = -1 - 4 = -5
Therefore, another endpoint of the segment is (-4, -5).
